Saudi Arabia says 12 people have died and more than 170 have been injured this week due to flooding from heavy rain in the northwest.

The Civil Defence said on Thursday that 10 people died in the area of Tabuk, one in Medina and another in the Northern Borders region. It did not say what caused the deaths.

Civil Defence forces say they rescued 271 people over the past four days, most of them in the al-Jawf region that borders Jordan. Several were also rescued in Mecca, Tabuk and the Northern Borders region.

Heavy rains have flooded desert valleys and forced schools to close. The English-language Arab News in Saudi Arabia posted video of water engulfing a street in the city of Medina, home to one of Islam’s holiest sites.
